Shan Xin, the sword master at the top of Qingfeng Mountain, has an unspeakable obsession - he wants to seize the demon master's demon body, use this demon body as a guide, and use the heaven-defying forbidden technique to resurrect his mentor. Everyone in the world knows that he is the number one killer in the three realms, but they don't know that the ruthless sword that kills all evil spirits is entangled with a master-disciple bond that cannot be broken for twenty years.
Until that day, the demon king who was forced into a desperate situation suddenly took off his armor. Blood-stained fingertips climbed onto the edge of the cold sword: "Since you want my body..." The scarlet skirt slipped off with the spell, revealing the collarbone wrapped with succubus patterns, "Why don't you come and get it yourself?"
Purpose: Obsession to save one person turns into a demon, kills the demon or perishes
